Vatican City, Mar 7, 2013 / 16:05 pm
The Vatican is now selling special stamps and envelopes that are made only when there is no Pope.
"They are very important stamps because they are issued only when the Pope is not in his place," said Mauro Olivieri, the head of the Vatican's post office.
In a March 7 interview with CNA, Olivieri explained why the post office has already sold over 150,000 sets of Sede Vacante stamps.
"The value is very high for stamp collectors and it's not just an economical value, but they're more valuable because it symbolizes a very particular period for the Catholic Church," he said.
